Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Alarm.com Holdings, Inc. (referred herein as “Alarm.com”, the “Company”, or “we”) is a cloud-based software platform solution for the connected home. Our multi-tenant software-as-a-service (“SaaS”) platform allows home and business owners to intelligently secure and manage their properties and remotely interact with a broad array of connected devices through a single, intuitive interface. Our solution is delivered through an established network of thousands of authorized and licensed service providers. Our four primary solutions are interactive security, intelligent automation, video monitoring and energy management, which can be used individually or integrated into a single user interface. We derive revenue from the sale of our software-as-a-service over our integrated platform, hardware, activation fees and other revenue. Our fiscal year ends on December 31st. Initial Public Offering On July 1, 2015, we closed our initial public offering ("IPO") of 7,000,000 shares of common stock at an offering price of $14.00 per share, resulting in gross proceeds of approximately $98.0 million . Our registration statement on Form S-1 relating to our IPO was declared effective by the Securities and Exchange Commission on June 25, 2015. In addition, on July 8, 2015, we closed the underwriters exercise of their over-allotment option to purchase 525,000 additional shares of our common stock from us, resulting in additional gross proceeds of approximately $7.4 million . We raised a total of $105.4 million in gross proceeds from the IPO, or approximately $93.0 million in net proceeds after deducting underwriting discount and commission of $7.4 million and offering costs of $5.0 million . The accompanying consolidated financial statements, including share and per share amounts, do not include the effects of the offering as it was completed subsequent to June 30, 2015. Upon completion of the IPO in the third quarter of 2015, (i) all outstanding shares of convertible preferred stock converted into an aggregate of 35,017,884 shares of common stock and (ii) we issued 7,525,000 shares of common stock resulting in net proceeds of $93.0 million after deducting the underwriters discount and offering costs. Dividend On June 12, 2015, our board of directors declared a cash dividend on our common and preferred stock in the amount of (1) $0.36368 per share of common stock and Series A preferred stock and (2) $0.72736 per share of Series B preferred stock and Series B-1 preferred stock or $20.0 million in the aggregate. The dividends were paid on June 26, 2015 to our stockholders of record as of June 12, 2015.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts and our results of operations and our majority owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes for the year ended December 31, 2014 appearing in our final prospectus filed with the SEC on June 26, 2015, pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The condensed balance sheet data as of December 31, 2014 was derived from our audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results that can be expected for the entire fiscal year ending December 31, 2015 . Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our estimates, judgments and assumptions are continually evaluated based on available information and experience. Because of the use of estimates inherent in the financial reporting process, actual results could differ from those estimates. Estimates are used when accounting for revenue recognition, allowances for doubtful accounts receivable, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, stock-based compensation, income taxes, legal reserves, contingent consideration and goodwill and intangible assets. Recent Accounting Pronouncements Adopted On April 10, 2014, the FASB issued ASU 2014-08, “ Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The guidance narrowed the definition of discontinued operations for disposal of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. The guidance also expands the scope to include equity method investments and businesses, that upon initial acquisition, qualify as held for sale. The expanded disclosure requirements include statement of financial position and statement of cash flows disclosures for all comparative periods. The ASU is effective prospectively for all disposals (or classifications as held for sale) in periods beginning on or after December 15, 2014 with early adoption permitted. We adopted this pronouncement in the first quarter of 2015 and it did not have a material impact on our financial statements. Not yet adopted On July 22, 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory,” which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). The guidance does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost provided that it is not above the ceiling (net realizable value) or below the floor (net realizable value less an approximately normal profit margin) which is unnecessarily complex. The amendment does not change other guidance on measuring inventory. The amendment is effective for annual periods, including periods within those annual periods beginning after December 15, 2016 with early adoption permitted. We are required to adopt this pronouncement prospectively in the first quarter of 2017 and we are currently assessing the impact of this pronouncement on our financial statements. On April 15, 2015, the FASB issued ASU 2015-05, “ Intangibles — Goodwill and Other — Internal- Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which clarifies the accounting for fees paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. The amendment requires a customer to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the customer would account for the fees related to the software license element in a manner consistent with how the acquisition of other software licenses is accounted for under ASC 350-40; if the arrangement does not contain a software license, the customer would account for the arrangement as a service contract. The guidance will not change GAAP for a customer’s accounting for service contracts. The amendment is effective for annual periods, including periods within those annual periods beginning after December 31, 2015 with early adoption permitted. We can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We are required to adopt this pronouncement in the first quarter of 2016 and we are currently assessing the impact of this pronouncement on our financial statements. On April 7, 2015, the FASB issued ASU 2015-03, “ Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The guidance in the new standard is limited to the presentation of debt issuance costs. The ASU is effective retrospectively for the presentation of debt issuance costs in periods beginning after December 15, 2015 with early adoption permitted. We are required to adopt this pronouncement in the first quarter of 2016 and we do not anticipate that adoption of the pronouncement will have a material impact on our financial statements. On February 18, 2015, the FASB issued ASU 2015-02, “ Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which requires an entity to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs"). The amendment eliminates the presumption that a general partner should consolidate a limited partnership. The amendment affects the consolidation analysis of reporting entities that are involved with VIEs particularly those that have fee arrangements and related party relationships. The amendment also provides a scope exception from consolidation guidance for reporting entities that comply with the requirements for registered money market funds. We are required to adopt ASU 2015-02 in the first quarter of 2016 and we do not anticipate that adoption of the pronouncement will have a material impact on our financial statements. On August 27, 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-4 0),” which requires management to perform interim and annual assessments regarding conditions or events that raise substantial doubt about a company’s ability to continue as a going concern and to provide related disclosures, if applicable. We are required to adopt ASU 2014-15 in the first quarter of 2017, with early adoption permitted. We do not anticipate that the adoption of this standard will have a material effect on our financial statements. On June 19, 2014, the FASB issued ASU 2014-12, “ Compensation — Stock Compensation (Topic 718),” which affects any entity that grants its employees share-based payments in which the terms of the award stipulate that a performance target that affects vesting could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. We are required to adopt ASU 2014-12 in the first quarter of 2016 and the adoption of this standard is not expected to have a material effect on our financial statements. On May 28, 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers (Topic 606),” which affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition guidance in Topic 605, “Revenue Recognition” , and most industry-specific guidance throughout the Industry Topics of the Codification. The guidance also supersedes some cost guidance included in Subtopic 605-35, “ Revenue Recognition — Contract-Type and Production-Type Contracts” . On April 1, 2015, the FASB voted to propose to defer the effective date of the pronouncement by one year, which was reaffirmed at the FASB July 9, 2015 meeting. ASU 2014-9, as amended, is effective for annual periods, and interim periods within those years, beginning after December 31, 2017. An entity is required to apply the amendments using one of the following two methods: (1) retrospectively to each prior period presented with three possible expedients: (a) for completed contracts that begin and end in the same reporting period no restatement is required; (b) for completed contract with variable consideration an entity may use the transaction price at completion rather than restating estimated variable consideration amounts in comparable reporting periods; and (c) for comparable reporting periods before date of initial application reduced disclosure requirements related to transaction price; (2) retrospectively with the cumulative effect of initially applying the amendment recognized at the date of initial application with additional disclosures for the differences of the prior guidance to the reporting periods compared to the new guidance and an explanation of the reasons for significant changes. We are required to adopt ASU 2014-09 in the first quarter of 2018 and we are currently assessing the impact of this pronouncement on our financial statements.

Business Combinations [Abstract]
Acquisitions	Acquisitions SecurityTrax Acquisition On March 13, 2015, in accordance with an asset purchase agreement, we completed our purchase of certain assets of HiValley Technology, Inc., (“SecurityTrax”) that constituted a business. SecurityTrax is a provider of SaaS-based, customer relationship management software tailored for security system dealers. The consideration included $ 5.6 million cash paid at closing and $ 0.4 million of cash not yet paid and established a contingent liability of $ 0.7 million for earn-out considerations to be paid to the former owners. The agreement also contains $ 2.0 million in potential payments associated with the continued employment of key employees through March 31, 2018 that will be accounted for as compensation expense over the period. We included the results of SecurityTrax’s operations since its acquisition date in the Alarm.com segment (see Note 18). The table below sets forth the consideration paid to SecurityTrax’s sellers and the estimated fair value of the tangible and intangible net assets acquired (in thousands): 2015 Calculation of Consideration: Cash paid, net of working capital adjustment $ 5,612 Cash not yet paid 400 Contingent consideration liability 700 Total consideration $ 6,712 Estimated Tangible and Intangible Net Assets: Current assets $ 14 Customer relationships 1,699 Developed technology 1,407 Trade name 271 Current liabilities (7 ) Goodwill 3,328 Total estimated tangible and intangible net assets $ 6,712 Goodwill of $ 3.3 million reflects the value of acquired workforce and expected synergies from pairing SecurityTrax solutions to security service providers with our offerings. The goodwill will be deductible for tax purposes. Our estimate of the fair value of intangible net assets was developed using a multi-period excess earnings method for customer relationships, the relief from royalty method for the developed technology, replacement cost method for the developed technology home page and the relief from royalty method for the trade name. Fair Value of Net Assets Acquired and Intangibles In accordance with ASC 805, the assets and liabilities of SecurityTrax we acquired were recorded at their respective fair values as of March 13, 2015, the date of the acquisition. Customer Relationships The customer relationships intangible was recorded separate from goodwill based on determination of the length, strength and contractual nature of the relationship that SecurityTrax shared with its customers. We valued two groups of customer relationships using the multi-period excess earnings method, an income approach. We used several assumptions in the income approach, including revenue growth, operating expenses, charge for contributory assets, and a 22.5 percent discount rate used to calculate the present value of the cash flows. For the second group of customer relationships, we used the same assumptions in addition to a customer retention rate of 90 percent . The customer relationships, valued at $ 1.7 million , are being amortized on a straight-line basis over a weighted-average estimated useful life of 7 years. Developed Technology Developed technology recorded separately from goodwill consists of intellectual property such as proprietary software used internally for revenue producing activities. SecurityTrax’s proprietary software is offered for sale on a SaaS hosted basis to customers. The developed technology was valued by applying the relief from royalty method, an income approach. We used several assumptions in the relief from royalty method, which included revenue growth, a market royalty rate of 25 percent and a 22.5 percent discount rate used to the calculate the present value of the cash flows. There was also an additional component of the developed technology that we refer to as the home page that organized customer data and functioned as the billing and administration tool. The home page component was valued by applying the replacement cost model, a cost approach. We used several assumptions in the replacement cost approach, which included analyzing costs that a company would expect to incur in order to recreate an asset of equivalent utility. In addition, there was an adjustment for developer’s profit of 30.4 percent which brought the asset to fair value on an exit-price basis. The developed technology, valued at $ 1.4 million , is being amortized on a straight-line basis over a weighted-average estimated useful life of 8 years. Contingent Consideration Liability The amount of contingent consideration liability to be paid, up to a maximum of $ 2.0 million , to the former owners will be determined based on revenue and EBITDA for the year ended December 31, 2017. We estimated the fair value of the contingent consideration liability by using a Monte Carlo simulation model for determining projected revenue by using an expected distribution of potential outcomes. The fair value of contingent consideration liability is calculated with thousands of projected revenue outcomes, the results of which are averaged and then discounted to estimate the present value. We used several assumptions including an 8.45% discount rate and a 7.5% revenue risk adjustment. The contingent consideration, valued at $ 0.7 million , was recorded as a contingent consideration liability in other liabilities in our consolidated balance sheet. The liability will be remeasured each reporting date with changes recorded in general and administrative expense until it is paid in the first quarter of 2018. As of the June 30, 2015 , the fair value of the contingent consideration liability was remeasured to $0.6 million using the same method with a 9.13% discount rate and a 7.5% revenue risk adjustment which resulted in a $0.1 million gain. Secure-i Acquisition On December 8, 2014, in accordance with an asset purchase agreement, we completed our purchase of certain assets of Secure-i, Inc. (“Secure-i”) that constituted a business. Secure-i is a provider of internet based remote video hosting services including off-site storage, viewing and management from web-based browsers and mobile applications. Total consideration included $ 2.6 million in cash and $ 0.3 million in cash not yet paid. We recorded $0.7 million of intangibles and $2.2 million of goodwill in connection with the acquisition. During the second quarter of 2015, we finalized the working capital adjustment and recorded an additional $20 thousand of goodwill. We included the results of Secure-i’s operations since its acquisition date in the Alarm.com segment. Horizon Analog Acquisition On December 10, 2014, in accordance with an asset purchase agreement, we completed our purchase of certain assets of Horizon Analog, Inc. (“Horizon Analog”) that constituted a business. Horizon Analog is a producer of research that focuses on cost-effective collection and analysis of data relating to energy usage and consumer behavior and energy disaggregation. Total consideration included $ 0.6 million in cash and $ 0.1 million in cash not yet paid. We recorded less than $ 0.1 million of property and equipment and $ 0.7 million of goodwill in connection with the acquisition, which reflects the acquired workforce and synergies expected from combining our operations with those of Horizon Analog. The goodwill will be deductible for tax purposes. We included the results of Horizon Analog’s operations since its acquisition date in the Alarm.com segment. Unaudited Pro Forma Information The following pro forma data is presented as if Secure-i, Horizon Analog and SecurityTrax were included in our historical consolidated statements of operations beginning January 1, 2014. These pro forma results do not necessarily represent what would have occurred if all the business combinations had taken place on January 1, 2014, nor do they represent the results that may occur in the future. This pro forma financial information includes our historical financial statements and those of our business combinations with the following adjustments: (1) we adjusted for amortization expense assuming the fair value adjustments to intangible assets had been applied beginning January 1, 2014; (2) we adjusted for $ 0.1 million of transaction costs incurred in 2015 and reclassified them to 2014 and (3) we included adjustments for income taxes associated with these pro forma adjustments. The pro forma adjustments were based on available information and upon assumptions that we believe are reasonable to reflect the impact of these acquisitions on our historical financial information on a supplemental pro forma basis, as follows (in thousands): Pro forma 2015 2014 Revenue $ 98,182 $ 79,740 Net income 5,512 6,046

Investments in Other Entities	Investments in Other Entities Cost Method Investment in Connected Home Service Provider On September 4, 2012, we purchased 20,000 Series A Convertible Preferred Membership Units of a Brazilian connected home solutions provider for $ 15.00 per unit, or $ 0.3 million , for a 12.2% interest on a fully diluted basis in this entity. On June 26, 2013, we entered into an agreement with the same company to purchase 2,667 Series B Convertible Preferred Membership Units at $ 26.22 per unit, or $ 0.1 million , which brought our aggregate interest to 12.4% on a fully diluted basis. On April 15, 2015, we entered into an additional agreement with the same company to purchase 2,333 Series B-1 Convertible Preferred Membership Units at $23.31 per unit or $0.1 million , which brought our aggregate equity interest to 12.6% on a fully diluted basis. The entity resells our products and services to residential and commercial customers in Brazil. Based upon the level of equity investment at risk, the connected home service provider is a VIE. We do not control the marketing, sales, installation, or customer maintenance functions of the entity and therefore do not direct the activities of the entity that most significantly impact its economic performance. We have determined that we are not the primary beneficiary of the entity and do not consolidate the connected home services provider. We account for this investment using the cost method. As of June 30, 2015 and December 31, 2014 , the fair value of this cost method investment was not estimated as there were no events or changes in circumstances that may have had a significant adverse effect on the fair value of the investment. The $ 0.4 million investment balance is included in other assets in our consolidated balance sheets as of June 30, 2015 and December 31, 2014 . Loans to and Investments in an Installation Partner On November 20, 2013, we paid $ 1.0 million to purchase 48,190 common units of an installation partner for a 48.2% interest on a fully diluted basis in this entity. The entity performs installation services for security dealers. Based upon the level of equity investment at risk, we determined that the installation partner is not a VIE. We account for this investment under the equity method because we have the ability to exercise significant influence over the operating and financial policies of the entity. Under the equity method, we recognize our share of the earnings or losses of the installation partner in other (expense) / income, net in our consolidated statements of operations in the periods they are reported by the installation partner. The loss in other (expense) / income, net was $ 0.1 million and $ 0.2 million for the three and six months ended June 30, 2015 . The loss in other (expense) / income, net was $ 0.1 million and $ 0.2 million for the three and six months ended June 30, 2014 . Our $ 1.0 million investment, net of equity losses, is included in other assets in our consolidated balance sheets and was $ 0.2 million and $ 0.4 million as of June 30, 2015 and December 31, 2014 . In September 2014, we loaned $ 315,000 to our installation partner under a secured promissory note that accrues interest at 8.0% . The note receivable is included in other assets in our consolidated balance sheets. Interest is payable monthly with the entire principal balance plus accrued but unpaid interest due at maturity in September 2016. This event did not cause us to reconsider our conclusion that the installation partner has sufficient equity investment at risk and therefore is not a VIE. We continue to account for the investment under the equity method. Loans to and Investments in a Platform Partner A platform partner produces connected devices that are integrated into our connected home platform, and we entered into investments to provide capital in order to bring our platform partner’s devices to market and integrate them onto our connected home platform. In the first quarter of 2013, we paid $ 3.5 million in cash to purchase 3,548,820 shares of our platform partner’s Series A convertible preferred shares, or an 18.7% interest on as-converted and fully diluted basis. In the fourth quarter of 2014, we entered into a Series 1 Preferred Stock purchase agreement with the platform partner and another investor. The other investor invested cash to purchase shares of the platform partner’s Series 1 Preferred Stock. As a result of the purchase, our 3,548,820 shares of Series A convertible preferred shares converted into 3,548,820 shares of common stock, and we hold an 8.6% interest in the platform partner on an as converted and fully diluted basis. In conjunction with the transaction, we received a $ 2.5 million dividend which we recorded as a return of investment as it was in excess of the accumulated earnings and profits of the investee since the date of the investment. Based upon the level of equity investment at risk, the platform partner is a VIE. We have concluded that we are not the primary beneficiary of the platform partner VIE. We do not control the product design, software development, manufacturing, marketing, or sales functions of the platform partner and, therefore, we do not direct the activities of the platform partner that most significantly impact its economic performance. We continue to conclude that we are not the primary beneficiary of our platform partner and, therefore, we do not consolidate it. We account for this investment under the cost method. As of June 30, 2015 , the fair value of this cost method investment was not estimated as there were no events or changes in circumstances that may have had a significant adverse effect on the fair value of the investment. As of June 30, 2015 and December 31, 2014 , our $ 1.0 million cost method investment in a platform partner was recorded in other assets in our consolidated balance sheets.

Other Assets	Other Assets Patent Licenses From time to time, we enter into agreements to license patents. We have $ 3.3 million in patent licenses related to two such agreements, which are being amortized over the estimated useful lives of the patents which range from three to eleven years. The net balance as of June 30, 2015 and December 31, 2014 was $ 2.4 million and $ 1.5 million . Amortization expense on patent licenses was $ 0.1 million for each of the three months ended June 30, 2015 and 2014 , was $ 0.1 million for each of the six months ended June 30, 2015 and 2014 . Loan to a Distribution Partner On July 25, 2013, we entered into a revolving loan agreement with a distribution partner. The distribution partner is also a service provider with whom we have a standard agreement to resell our connected home service and hardware. We evaluate the credit quality of our distribution partner for purposes of the revolving loan agreement using the same methods that we employ to evaluate its creditworthiness as a service provider, including a credit review at the inception of the arrangement and if risk indicators arise. At the inception of the loan agreement, we determined the credit quality of our distribution partner to be good. No risk indicators have arisen to cause us to change that assessment. Under the terms of the revolving loan agreement, we agreed to loan our distribution partner up to $ 2.8 million , with the proceeds of the loan used to finance the creation of new customer accounts that use our products and services. The amount that our distribution partner may draw down on the loan is based on the number of its qualifying new customer accounts created each month. The loan bears interest at a rate of 8.0% per annum, and requires monthly interest payments, with the entire principal balance due on the loan maturity date, July 24, 2018. The balance outstanding under the loan is collateralized by the customer accounts owned by our distribution partner, as well as all of the physical assets and accounts receivable associated with those customer accounts. As of June 30, 2015 and December 31, 2014 , our distribution partner has borrowed $ 2.2 million and $ 2.0 million under this loan agreement, respectively, and this note receivable is included in other assets on our consolidated balance sheets. Deferred Offering Costs Deferred offering costs of $5.0 million and $ 2.8 million consisting primarily of legal and accounting fees, are included in other assets on the consolidated balance sheets as of June 30, 2015 and December 31, 2014 . Upon the closing of our IPO these amounts will be offset against the proceeds of the offering and will be included in stockholders’ (deficit) equity.

The liability for the subsidiary unit awards relates to agreements established with the presidents of two of our subsidiaries, who are employees, for cash awards contingent upon the subsidiary companies meeting certain financial milestones. Prior to our IPO, we used the intrinsic method available to non-public companies under ASC 718, Compensation - Stock Compensation to account for our liability for our subsidiary units. During the three months ended June 30, 2015, we have accounted for these subsidiary awards using fair value. The effect of this change had an immaterial impact to our consolidated financial statements. We established liabilities for the future payment for the repurchase of subsidiary units under the terms of the agreements based on estimating revenue, working capital, EBITDA and EBITDA margin for the periods of the two awards. We estimated the fair value of each liability by using a Monte Carlo simulation model for determining each of the projected measures by using an expected distribution of potential outcomes. The fair value of each liability is calculated with thousands of projected outcomes, the results of which are averaged and then discounted to estimate the present value. These liabilities will be remeasured each reporting date until the respective payment dates with the same valuation approach with changes in general and administrative expense. The liability balances are included in our other liabilities in our consolidated balance sheets. The amount of contingent consideration liability to be paid, up to a maximum of $ 2.0 million , from our acquisition of SecurityTrax in the first quarter of 2015, will be determined based on revenue and adjusted EBITDA for the year ended December 31, 2017. We estimated the fair value of the contingent consideration liability by using a Monte Carlo simulation model for determining projected revenue by using an expected distribution of potential outcomes. The fair value of contingent consideration liability is calculated with thousands of projected revenue outcomes, the results of which are averaged and then discounted to estimate the present value. The contingent consideration liability will be remeasured each reporting date until payment in first quarter of 2018 with the same valuation approach using our subsidiary’s revenue, an unobservable input, with changes in general and administrative expense. The contingent consideration liability balance is included in our other liabilities in our consolidated balance sheets. We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. There were no transfers between Levels 1, 2 or 3 during the three and six months ended June 30, 2015 and 2014 . We also monitor the value of the investments for other-than-temporary impairment on a quarterly basis. No other-than-temporary impairments occurred during the three and six months ended June 30, 2015 and 2014 .

Debt, Commitments and Contingencies Disclosure [Abstract]
Debt, Commitments and Contingencies	Debt, Commitments and Contingencies The debt, commitments and contingencies described below are currently in effect and would require us, or our subsidiaries, to make payments to third parties under certain circumstances. Debt On May 8, 2014, we repaid all of the outstanding principal and interest under our previous term loan, which was accounted for as an extinguishment of debt, and replaced it with a $ 50.0 million revolving credit facility (the “2014 Facility”) with Silicon Valley Bank, as administrative agent, and a syndicate of lenders. We utilized $ 6.7 million under this facility to repay in full our indebtedness under our previous term loan. The 2014 Facility includes an option to increase the borrowing capacity available under the 2014 Facility to $ 75.0 million with the consent of the lenders. The 2014 Facility is available to us to finance working capital and certain permitted acquisitions and investments, and is secured by substantially all of our assets, including our intellectual property. The principal outstanding under the 2014 Facility is due upon maturity in May 2017. The outstanding principal balance on the 2014 Facility accrues interest at a rate equal to either (1) the Eurodollar Base Rate, or LIBOR, plus an applicable margin based on our consolidated leverage ratio, or (2) the higher of (a) the Wall Street Journal prime rate and (b) the Federal Funds rate plus 0.50% plus an applicable margin based on our consolidated leverage ratio, or ABR, at our option. Borrowings under LIBOR rates accrue interest at LIBOR plus 2.25% , LIBOR plus 2.5% , and LIBOR plus 2.75% when our consolidated leverage ratio is less than or equal to 1.00 :1.00, greater than or equal to 1.00 :1.00 but less than 2.00 :1.00, and greater than 2.00 :1.00, respectively. Borrowings under ABR rates accrue interest at ABR plus 1.25% , ABR plus 1.5% , and ABR plus 1.75% when our consolidated leverage ratio is less than or equal to 1.00 :1.00, greater than or equal to 1.00 :1.00 but less than 2.00 :1.00, and greater than 2.00 :1.00, respectively. The 2014 Facility also carries an unused line commitment fee of 0.20% to 0.25% depending on our consolidated leverage ratio. For the six months ended June 30, 2015 , the effective interest rate on the 2014 Facility was 2.51% . The carrying value of 2014 Facility was $ 6.7 million as of June 30, 2015 and December 31, 2014. The 2014 Facility includes a variable interest rate that approximates market and, as such, we determined that the carrying amount of the 2014 Facility approximates its fair value. The 2014 facility contains various financial and other covenants that require us to maintain a maximum consolidated leverage ratio not to exceed 2.50 :1.00 and a consolidated fixed charge coverage ratio of at least 1.25 :1.00. During the six months ended June 30, 2015 , we were in compliance with all financial and non-financial covenants and there were no events of default. Commitments and Contingencies Repurchase of Subsidiary Units In September 2012, we formed a subsidiary to develop and market home and commercial energy management devices and services. We granted an award of subsidiary stock to the founder and president. The terms of the award for the founder, who is also our employee, require a payment in cash on either the third or the fourth anniversary from the date the subsidiary first makes its products and services commercially available, which was determined to be April 1, 2014. The vesting of the award is based on the subsidiary meeting certain minimum financial targets. We recorded a liability of $0.0 million related to this commitment in other liabilities in our consolidated balance sheets as of June 30, 2015 and December 31, 2014 . In February 2011, we formed a subsidiary that offers professional residential property management and vacation rental management companies technology solutions for remote monitoring and control of properties, including access control and energy management. We granted an award of subsidiary stock awards to the founder and president. The terms of the award for the founder, who is our employee, require a payment in cash on between the fourth and sixth anniversary of the date that the subsidiary’s products and services first become commercially available, which was determined to be June 1, 2013. The vesting of the award is based on the subsidiary meeting certain minimum financial targets. We have recorded a liability of $ 0.1 million and $ 0.2 million related to the commitment in other liabilities in our consolidated balance sheets as of June 30, 2015 and December 31, 2014 . These liabilities will be remeasured each reporting date until the respective payment dates with changes in fair value recorded in general and administrative expense. The liability balances are included in our other liabilities in our consolidated balance sheets. Leases We lease office space and office equipment under non-cancelable operating leases with various expiration dates through 2026. Rent expense was $ 1.2 million and $ 2.4 million for the three and six months ended June 30, 2015 and $ 0.4 million and $ 0.8 million for the three and six months ended June 30, 2014 . Indemnification Agreements We have various agreements where we may be obligated to indemnify the other party to the agreement with respect to certain matters. Generally, these indemnification provisions are included in contracts arising in the normal course of business. Although it is not possible to predict the maximum potential amount of future payments that may become due under these indemnification agreements, we do not believe any potential liability that might arise from such indemnity provisions is probable or material. Legal Proceedings On June 2, 2015, Vivint, Inc. filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking preliminary and permanent injunctions, enhanced damages and attorney’s fees. We answered the complaint on July 23, 2015. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. Should Vivint prevail on its claims that one or more elements of our solution infringe one or more of its patents, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution, enjoined from making, using, and selling our solution if a license or other right to continue selling such elements is not made available to us or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of the legal claim and proceeding against us cannot be predicted with certainty. We believe we have valid defenses to Vivint’s claims. Based on currently available information, we determined a loss is not probable or reasonably estimable at this time. In addition, from time to time, we are a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. We are not a party to any lawsuit or proceeding that, in the opinion of management, is reasonably possible or probable of having a material adverse effect on its financial position, results of operations or cash flows. We reserve for contingent liabilities based on ASC 450, “ Contingencies ,” when it is determined that a liability, inclusive of defense costs, is probable and reasonably estimable. Litigation is subject to many factors that are difficult to predict, so there can be no assurance that, in the event of a material unfavorable result in one or more claims, we will not incur material costs.

Employee Benefit Plans	Employee Benefit Plans Employee Stock Purchase Plan We adopted the Employee Stock Purchase Plan (the "2015 ESPP") in June 2015. Under the 2015 ESPP, 1,200,000 shares have been initially reserved for future grant with provisions established to increase the number of shares available on January 1 of each subsequent year for nine years. The annual automatic increase in the number of shares available for issuance under the 2015 ESPP is the lesser of 1% of each class of common stock outstanding as of December 31 of the preceding fiscal year, 1,500,000 shares of common stock or such lesser number as determined by the board of directors. The ESPP will allow eligible employees to purchase shares of our common stock through payroll deductions at a discount not to exceed 10% of the market value on the date of each purchase period. The maximum number of shares of our common stock that a participant may purchase during any calendar year for the 2015 ESPP shall not exceed such number of shares having a fair market value equal to the lesser of $15,000 or 10% of the participant's base compensation for that year. The ESPP is considered compensatory for purposes of share-based compensation expense. For the six months ended June 30, 2015, no shares were purchased by employees and we did not recognize compensation for the 2015 ESPP. As of June 30, 2015, 1,200,000 shares remain available for future issuance. Stock-Based Compensation Stock Options In June 2015, our board of directors adopted, our stockholders approved, and we registered the shares for the 2015 Equity Incentive Plan (the "2015 Plan"), pursuant to which we initially reserved 4,700,000 shares of common stock for issuance to our employees, directors, and non-employee directors and consultants including 141,222 shares of our common stock previously reserved for issuance under our Amended and Restated 2009 Stock Incentive Plan (the "2009 Plan") that were added to the shares reserved under the 2015 Plan upon its effectiveness. The 2015 Plan provides for the grant of incentive stock options to employees and for the grant of nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensations to employees, directors and non-employee directors and consultants. The number of shares of common stock reserved for issuance under the 2015 Plan will automatically increase on January 1 each year, for a period of not more than ten years, commencing on January 1, 2015 through January 1, 2024, by 5% of the total number of shares of common stock outstanding on December 31st of the preceding calendar year, or a lesser number of shares as may be determined by the board of directors. As a result of the adoption of the 2015 Plan, no further grants may be made under the 2009 Plan described below. As of June 30, 2015 we had not made any grants under the 2015 Plan, such that 4,700,000 shares remained available for future grant. The 2009 Plan provided for the grant of incentive stock options to employees and for the grant of nonqualified stock options and restricted stock to our employees, directors and non-employee directors and consultants. Stock options have been granted at exercise prices as determined by the board of directors to our officers and employees. These stock options generally vest over a five year period and each option, if not exercised or terminated, expires on the ten th anniversary of the grant date. The 2009 Plan allows for the granting of options that may be exercised before the options have vested. Unvested shares issued as a result of early exercise are subject to repurchase by us upon termination of employment or services at the original exercise price. The proceeds from the early exercise of stock options are initially recorded as a current liability and are reclassified to common stock and additional paid-in capital as the awards vest and our repurchase right lapses. As of June 30, 2015 , there were 156,009 unvested shares of common stock outstanding subject to our right of repurchase. As of December 31, 2014 , there were 209,372 unvested shares of common stock outstanding subject to our right of repurchase. During the six months ended June 30, 2015 , we repurchased 287 unvested shares of common stock related to early exercised stock options in connection with employee terminations. As of June 30, 2015 and December 31, 2014 , we recorded $ 0.6 million and $ 0.7 million in accounts payable, accrued expenses and other current liabilities on the consolidated balance sheets for the proceeds from the early exercise of the unvested stock options. Included in the stock-based compensation expense for the three and six months ended June 30, 2015 was $0.8 million related to the cash settlement of recently exercised stock options of a terminated employee, at the company's election. We accounted for this cash settlement as a liability modification of the stock option awards. We account for stock-based compensation awards based on the fair value of the award as of the grant date. We recognize stock-based compensation expense using the accelerated attribution method, net of estimated forfeitures, in which compensation cost for each vesting tranche in an award is recognized ratably from the service inception date to the vesting date for that tranche. The following table summarizes the components of stock-based compensation expense for the three and six months ended June 30, 2015 and 2014 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Stock options $ 656 $ 809 $ 1,196 $ 1,576 Compensation related to the sale of common stock 172 22 193 43 Compensation related to modification of stock options 777 — 777 — Total equity based compensation expense $ 1,605 $ 831 $ 2,166 $ 1,619 Tax benefit from stock-based awards $ 396 $ 57 $ 241 $ 748 Stock-based compensation expense is included in the following line items in the accompanying consolidated statements of operations for the three and six months ended June 30, 2015 and 2014 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Sales and marketing $ 86 $ 78 $ 146 $ 155 General and administrative 1,226 482 1,520 962 Research and development 293 271 500 502 Total stock-based compensation expense $ 1,605 $ 831 $ 2,166 $ 1,619 There were 482,276 stock options granted during the six months ended June 30, 2015 . The dividends declared and paid during six months ended June 30, 2015 were in anticipation of our IPO, which we closed on July 1, 2015. Subsequent to the IPO, we do not expect to declare or pay dividends on a recurring basis. As such, we assume that the dividend rate is zero . The following table summarizes the assumptions used for estimating the fair value of stock options granted during the three and six months ended June 30, 2015 and 2014 : Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Volatility 48.5 - 51.8% 49.4 - 49.5% 48.5 - 51.8% 48.0 - 49.6% Expected term 4.5 - 5.7 years 5.8 - 6.3 years 4.5 - 5.7 years 4.0 - 5.7 years Risk-free interest rate 1.3 - 1.6% 2.0 - 2.1% 1.3 - 1.6% 1.4 - 1.9% Dividend rate — % — % — % — % The following table summarizes the stock option activity for the six months ended June 30, 2015 : Number of Options Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (in years) Aggregate Intrinsic Value (in thousands) Outstanding at December 31, 2014 3,345,993 $ 2.68 7.0 $ 27,725 Granted 482,276 11.55 — Exercised (202,005 ) 1.53 1,997 Forfeited (24,407 ) 3.79 — Cancelled (4,326 ) 1.46 — Outstanding at June 30, 2015 3,597,531 $ 3.93 7.0 $ 41,186 Vested and expected to vest at June 30, 2015 3,545,624 $ 3.89 7.0 $ 40,751 Exercisable at June 30, 2015 1,785,877 $ 1.58 5.5 $ 24,641 The weighted average grant date fair value for our stock options granted during the six months ended June 30, 2015 was $ 11.55 . There were 482,276 stock options granted during the six months ended June 30, 2015 . The total fair value of stock options vested during the six months ended June 30, 2015 and 2014 was $ 0.8 million and $ 0.3 million . The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2015 and 2014 was $ 2.0 million and $ 6.9 million . As of June 30, 2015 , the total compensation cost related to nonvested awards not yet recognized was $ 4.5 million , which will be recognized over a weighted average period of 2.3 years. Warrants In 2010, we issued a performance-based warrant to an executive officer that gives this individual the right to purchase up to 91,881 shares of our common stock in the aggregate if certain performance targets and market conditions are achieved. In 2012, we issued an additional performance-based warrant to an executive officer that gives that executive officer the right to purchase up to 27,000 shares of our common stock if certain performance targets and market conditions are achieved. On March 30, 2015, we issued performance-based warrants to two employees. These warrants give these individuals the right to purchase up to 54,694 shares of our common stock in the aggregate if certain performance targets are achieved. The first performance-based warrant for 91,881 shares of our common stock has an exercise price of $ 0.41 per share and becomes exercisable if we have a change in control or if we complete an initial public offering. This warrant for 91,881 shares of our common stock expired in May 2015 upon the cessation of the holder of the warrant's employment with us. The second performance-based warrant for 27,000 shares of our common stock has an exercise price of $ 3.89 per share and becomes exercisable if we have a change in control or if we complete an initial public offering. This warrant expired in July 2015 as the holder of the warrant did not meet the minimum annual revenue and EBITDA targets required during the exercise period. The exercise period began upon the occurrence of a triggering event, which occurred on June 25, 2015, upon the effectiveness of our registration statement, and closed thirty days subsequent to the effectiveness of our registration statement. The third and fourth performance-based warrants, each for 27,347 shares of our common stock, have an exercise price of $ 10.97 per share and we may elect to terminate the warrants in exchange for a one-time cash settlement in the event of a change in control. If the warrants become exercisable, the number of shares that become exercisable is based upon the achievement of certain minimum annual revenue targets, not to exceed a maximum of 27,347 shares for each warrant. These warrants will expire upon the earlier of March 2025 and the date upon which the holder of the warrant is no longer our employee or an employee of an affiliate of ours. We believe that the achievement of the minimum annual revenue targets is probable and we began recognizing expense related to these performance-based warrants on April 1, 2015. As of June 30, 2015 and December 31, 2014 , none of the warrants which remained outstanding were exercisable as the performance requirements had not been met. We recorded $0.0 million of expense associated with the performance-based warrants during the three months ended June 30, 2015 and 2014 and $0.0 million of expense associated with the performance-based warrants during the six months ended June 30, 2015 and 2014 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For purposes of interim reporting, our annual effective income tax rate is estimated in accordance with ASC 740-270, Interim Reporting . This rate is applied to the pre-tax book income of the entities expected to be benefited during the year. Discrete items that impact the tax provision were recorded in the period incurred. Our effective income tax rates were 39.9% and 40.8% for the three months ended June 30, 2015 and 2014 and 40.1% and 40.0% for the six months ended June 30, 2015 and 2014 . Our effective tax rate differs from the statutory rate primarily due to the impact of state taxes and non-deductible meal and entertainment expenses. A valuation allowance is recognized if, based on the weight of available evidence, both positive and negative, it is more likely than not that some portion, or all, of net deferred tax assets will not be realized. Based on our historical and expected future taxable earnings, we believe it is more likely than not that we will realize all of the benefit of the existing deferred tax assets at June 30, 2015 and December 31, 2014 . Accordingly, we have not recorded a valuation allowance as of June 30, 2015 and December 31, 2014 . We apply guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, this guidance permits us to recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is more likely than not to be realized upon settlement. For the three and six months ended June 30, 2014 , we had no unrecorded tax benefits for uncertain tax positions. During 2014 , we recorded an unrecognized tax benefit of $ 0.2 million related to research and development tax credits we claimed for tax years 2012 , 2013 and 2014 . For the three and six months ended June 30, 2015 , the only change to this year-end balance was the recording of additional interest for the quarter.

Related Party Transactions	Related Party Transactions Our installation partner, in which we have a 48.2% ownership interest, performs installation services for security dealers and also provides installation services for us and certain of our subsidiaries. We account for this investment using the equity method (see Note 7). During the six months ended June 30, 2015 and 2014 , we recorded $0.3 million and $ 0.3 million of cost of hardware and other revenue in connection with this installation partner and, as of June 30, 2015 and December 31, 2014 the accounts payable balance was $ 0.1 million and $ 0.1 million . In September 2014, we loaned $ 315,000 to our installation partner under a secured promissory note that accrues interest at 8.0% . Interest is payable monthly with the entire principal balance plus accrued but unpaid interest due at maturity in September 2016. For the three and six months ended June 30, 2015, we recorded $6,000 and $ 11,000 of interest income related to this note receivable. In June 2015, two of our significant stockholders, entities affiliated with Technology Crossover Ventures ("TCV"), and entities affiliated with ABS Capital Partners ("ABS"), entered into a Securities Purchase Agreement (the "Secondary Sale Agreement"). Pursuant to the terms of the Secondary Sale Agreement, ABS agreed to sell to TCV and TCV agreed to buy from ABS, 888,988 shares of our common stock at a purchase price of $13.02 per share.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts and our results of operations and our majority owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes for the year ended December 31, 2014 appearing in our final prospectus filed with the SEC on June 26, 2015, pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The condensed balance sheet data as of December 31, 2014 was derived from our audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results that can be expected for the entire fiscal year ending December 31, 2015 .
Use of Estimates	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our estimates, judgments and assumptions are continually evaluated based on available information and experience. Because of the use of estimates inherent in the financial reporting process, actual results could differ from those estimates. Estimates are used when accounting for revenue recognition, allowances for doubtful accounts receivable, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, stock-based compensation, income taxes, legal reserves, contingent consideration and goodwill and intangible assets.
Recent Accounting Pronouncements	Adopted On April 10, 2014, the FASB issued ASU 2014-08, “ Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The guidance narrowed the definition of discontinued operations for disposal of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. The guidance also expands the scope to include equity method investments and businesses, that upon initial acquisition, qualify as held for sale. The expanded disclosure requirements include statement of financial position and statement of cash flows disclosures for all comparative periods. The ASU is effective prospectively for all disposals (or classifications as held for sale) in periods beginning on or after December 15, 2014 with early adoption permitted. We adopted this pronouncement in the first quarter of 2015 and it did not have a material impact on our financial statements. Not yet adopted On July 22, 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory,” which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). The guidance does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost provided that it is not above the ceiling (net realizable value) or below the floor (net realizable value less an approximately normal profit margin) which is unnecessarily complex. The amendment does not change other guidance on measuring inventory. The amendment is effective for annual periods, including periods within those annual periods beginning after December 15, 2016 with early adoption permitted. We are required to adopt this pronouncement prospectively in the first quarter of 2017 and we are currently assessing the impact of this pronouncement on our financial statements. On April 15, 2015, the FASB issued ASU 2015-05, “ Intangibles — Goodwill and Other — Internal- Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which clarifies the accounting for fees paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. The amendment requires a customer to determine whether a cloud computing arrangement contains a software license. If the arrangement contains a software license, the customer would account for the fees related to the software license element in a manner consistent with how the acquisition of other software licenses is accounted for under ASC 350-40; if the arrangement does not contain a software license, the customer would account for the arrangement as a service contract. The guidance will not change GAAP for a customer’s accounting for service contracts. The amendment is effective for annual periods, including periods within those annual periods beginning after December 31, 2015 with early adoption permitted. We can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We are required to adopt this pronouncement in the first quarter of 2016 and we are currently assessing the impact of this pronouncement on our financial statements. On April 7, 2015, the FASB issued ASU 2015-03, “ Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The guidance in the new standard is limited to the presentation of debt issuance costs. The ASU is effective retrospectively for the presentation of debt issuance costs in periods beginning after December 15, 2015 with early adoption permitted. We are required to adopt this pronouncement in the first quarter of 2016 and we do not anticipate that adoption of the pronouncement will have a material impact on our financial statements. On February 18, 2015, the FASB issued ASU 2015-02, “ Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which requires an entity to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs"). The amendment eliminates the presumption that a general partner should consolidate a limited partnership. The amendment affects the consolidation analysis of reporting entities that are involved with VIEs particularly those that have fee arrangements and related party relationships. The amendment also provides a scope exception from consolidation guidance for reporting entities that comply with the requirements for registered money market funds. We are required to adopt ASU 2015-02 in the first quarter of 2016 and we do not anticipate that adoption of the pronouncement will have a material impact on our financial statements. On August 27, 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-4 0),” which requires management to perform interim and annual assessments regarding conditions or events that raise substantial doubt about a company’s ability to continue as a going concern and to provide related disclosures, if applicable. We are required to adopt ASU 2014-15 in the first quarter of 2017, with early adoption permitted. We do not anticipate that the adoption of this standard will have a material effect on our financial statements. On June 19, 2014, the FASB issued ASU 2014-12, “ Compensation — Stock Compensation (Topic 718),” which affects any entity that grants its employees share-based payments in which the terms of the award stipulate that a performance target that affects vesting could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. We are required to adopt ASU 2014-12 in the first quarter of 2016 and the adoption of this standard is not expected to have a material effect on our financial statements. On May 28, 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers (Topic 606),” which affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition guidance in Topic 605, “Revenue Recognition” , and most industry-specific guidance throughout the Industry Topics of the Codification. The guidance also supersedes some cost guidance included in Subtopic 605-35, “ Revenue Recognition — Contract-Type and Production-Type Contracts” . On April 1, 2015, the FASB voted to propose to defer the effective date of the pronouncement by one year, which was reaffirmed at the FASB July 9, 2015 meeting. ASU 2014-9, as amended, is effective for annual periods, and interim periods within those years, beginning after December 31, 2017. An entity is required to apply the amendments using one of the following two methods: (1) retrospectively to each prior period presented with three possible expedients: (a) for completed contracts that begin and end in the same reporting period no restatement is required; (b) for completed contract with variable consideration an entity may use the transaction price at completion rather than restating estimated variable consideration amounts in comparable reporting periods; and (c) for comparable reporting periods before date of initial application reduced disclosure requirements related to transaction price; (2) retrospectively with the cumulative effect of initially applying the amendment recognized at the date of initial application with additional disclosures for the differences of the prior guidance to the reporting periods compared to the new guidance and an explanation of the reasons for significant changes. We are required to adopt ASU 2014-09 in the first quarter of 2018 and we are currently assessing the impact of this pronouncement on our financial statements.
